The Watchdog Timer (WDT) has a prescaler generating a time-out period. This prescaler is
clocked from the RC oscillator. The watchdog timer must be periodically reset by software within
the time-out period, otherwise, the device is reset and starts executing from the boot vector. This
allows the device to recover from a condition that has caused the system to be unstable.
Figure 11-1. WDT Block Diagram
In order to use this module, other parts of the system must be configured correctly, as described
below.
When the WDT is enabled, the WDT remains clocked in all sleep modes, and it is not possible to
enter Static mode.
The WDT can use the system RC oscillator (RCSYS) as clock source. This oscillator is always
enabled whenever these modules are active. Please refer to the Electrical Characteristics chap-
ter for the characteristic frequency of this oscillator (f
The WDT prescaler is frozen during debug operation, unless the On-Chip Debug (OCD) system
keeps peripherals running in debug operation.
